With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved door stop embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

FIG. 1 illustrates a prior art door stop, as presented in design patent U.S. Pat. No. 286,015.

FIG. 2 sets forth a prior art door stop apparatus 2 presented in U.S. Pat. No. 4,831,688, wherein the "U" shaped body of the apparatus is positioned overlying a main body portion of a hinge 3 within a door gap 6 defined between a door frame 4 and a door 5.

More specifically, the door stop 10 of the instant invention essentially comprises a first plate 11 mounted to a second plate 12 along a joinder line 17 defining a "V" shaped body. The respective first and second plates define respective first and second top surfaces 11a and 12a and should be noted the plates are coextensive relative to one another of equal configuration. An acute angle 13 is defined between the first and second plates, wherein an "L" shaped support leg 14 extends rearwardly relative to the "V" shaped body and bisects the angle 13 in its rearward extent, and includes a first leg 15 that is coplanar with the respective first and second top surfaces 11a and 12a. A second leg 16 orthogonally joined to the first leg 15 extends parallel to the joinder line 17. In this manner, the support leg 14 is positional overlying a hinge central body portion 3, in a manner as illustrated in the prior art structure of FIG. 2, with the "V" shaped plates 11 and 12 extending within the door gap 6 in use.

FIGS. 7 and 8 illustrate the use of a modified door stop 10, wherein a threaded shank 18 is formed at a lower terminal end of a modified second leg 16a of a modified "L" shaped leg 14a. The threaded shank 18 threadedly receives an internally threaded magnetic tube 19 to enhance mounting and magnetic attraction of the "L" shaped leg to the hinge. It should be further noted that a predetermined degree of flexure is accommodated by the "V" shaped body and the joinder line 17 which functions as means to maintain the "V" shaped body in an extended configuration and permits a certain degree of compression between the first and second plates. The modified door stop 10a includes a respective first and second wing 20 and 21 to define acute angles between the respective first and second plates 11 and 12 and defines a generally "W" shaped body, including respective first and second abutment rods 22 and 23 mounted at opposed vertical end portions of the first and second wings, wherein the abutment rods are arranged parallel to the joinder line 17. The "W" shaped body accommodates a greater degree of flexure in association within the door gap 6.
